通过分析科技金融政策的作用机理,并借鉴不同层面的创新效率评价范式,构建针对科技型中小企业创新效率评价的投入-产出指标体系。以天津地区的科技型中小企业为研究对象,通过问卷进行数据挖掘,实现政策投入的具体量化,并利用DEA-BCC模型对企业创新效率进行评价。研究发现,科技型中小企业对创新资源的利用效率较高,但迫于规模约束,投入冗余情况较为严重,尚未实现资源优化配置,导致企业整体创新效率水平低下；随生命周期发展阶段的推进,企业创新效率总体呈现上升趋势；相比传统行业而言,处于新兴行业的企业资源利用水平更优；国有控股背景的企业在整体创新效率和资源配置方面更具优势。

Based on mechanism analysis of the science and technology financial policies, and existing research results about innovation efficiency evaluation, the input- output indicator system, which took the policy element into consideration, was built. Data mining was implemented through the questionnaire survey. Then the efficiency of technology-based small and medium-sized enterprises (SMEs) was evaluated by using DEA-BCC model. The results showed that technology-based SMEs in Tianjin region performed efficiently in the use of innovation resources, but due to size constraints, optimal allocation of resources was not yet achieved. The phenomenon of input redundancy and output deficiency is obvious. Besides as the life stage developed, innovation efficiency presented a general increasing tendency. Compared with those in traditional industry, the technology-based SMEs in emerging industry presented higher efficiency in the use of innovation resources. The state-owned technology-based SMEs were more outstanding in terms of innovation capability and resource allocation.
